So far we love it! Takes longer than it says to reach the set temp especially in cold weather so if we want to use it in evening we turn the temp up in the AM. Normally we set it at 100 to reduce electricity use. We also bought an inflatable bladder to put on top (under the provided soft lid) to prevent the pooling of rain water which then cools down the tub when not in use. Helps to insulate. Also we put a foam base beneath the tub to help insulate and protect from any sharp bits that could be on the ground. Oh lastly the filter that needs to be changed Or cleaned every 180 hours— will start beeping incessantly and the heater will turn off until you change it/reset it. So we just set a date and time weekly for the filter care to prevent that from happening. So far so good!! Well worth the $$ as long as it lives a season or two!
